A feature missing from the app is a passcode to open the app.If someone steals or finds your phone, then they have access to your home network.Then they can make all kinds of changes and create a mess. I dont want someone to find my phone and then have fun turning my lights on and off.

Please add an option to have a highly secure passcode to open the app.

@Twomoon: Rather than a 3rd party app, a pin lock, pattern, or other method for your phone entirely would probably be a better fit. The Almond app may allows them to change your network and lights/etc but only until you reset the router (worst case). If you had your email or other accounts on phone, you could be in much worse shape in general.
